Big Dream for a small navy by Tzoli Big Dream for a small navy by Tzoli
Before the First World War The Romanian Navy wanted to expand it's capacity so a plan was initiated in 1912:
This called for 6 Light Cruisers of 3500ton (None begun) 12 Destroyers of 1500ton of which 4 started and only 2 arrived and one submarine. Other plans were even more unrealistic calling for a battleship of 13.000tons armed with 4-305mm, 4-203mm and 12-150mm Guns.

So I decided to draw this Romanian Battleship Proposal which I call Bucaresti Class and based on the Austro-Hungarian Radetzky class.
It is only a bit smaller, changed the twin 240mm Turrets into single 203mm ones, 1000 nautical mile less range and one large single funnel instead of two smaller ones.

Awesome stuff. Like the Chinese vessel, this was actually real planned? Even your drawing is based at impressions?

Real dream of the Romanian navy.
There were no drawings (or none survived) so I based it on the Radetzky class which is similar in armaments, though the single funnel I'm not sure, it's my idea for one large funnel instead of two smaller

So did they prefered the reciprocating engines than the turbines...

Well I just used the Radetzky as a basis which had VTE, maybe I change the engines to turbines

Ahn, okies ;) That transition times many navies still used the triple expansion ones ^^

Romanian pre dreadnought... nice!
I'm not really informed on the romanian navy... did they ever had capital ships like this?

Nope, their largest ships are the Cruiser Elisabeta and the Guided Missile Destroyer Marsesti:

It is more like a pre dreadnought style battleship in the age of dreadnought as the requirements were made for a ship in 1912

yes, in 1912 everybody had switched to dreadnoughts, but Romania doesn't have that much coastal territory... I guess a dreadnought like a modified Viribus Unitis would have been kind of useless.
